[openstack][cinder] volume_copy_bps_limit

Hello stackers,
I am using cinder netapp nfs driver and I have vm performances problems
during the backup of volumes.
My backup tool make snapshots of volumes, then, on compute notes, it use
virt-convert for creating a volume backup on another nfs backend using a
different vlan.
But during the virt-convert a lot of read are done on netapp and my virtual
machines become very slow.
I am asking if volume_copy_bps_limit can help me to mitigate.

Please, anyone could help me ?
Ignazio
